INDOOR PORTABLE OSCILLATING DRIER Filed May 26, 1950 ERNEST K. F CHON BYAT To RN evs Patented Nov. i3, 1951 UNITED STATES PATENT OFFICE INDOORPORTABLE OSCILLATING DRIER Ernest K. F. Chun, Honolulu, Territory ofHawaii Application May 26, 1950, Serial No. 164,461

1 Claim. 1

This invention relates to drying apparatus, and more particularly to anoscillating drier which is electrically operated.

A main object of the invention is to provide a novel and improvedelectrically operated, indoor drying apparatus which is very simple inconstruction, which involves relatively few parts, and which is verysimple to operate.

A iur-ther object of the invention is to provide an improved electricaldrying apparatus which is very inexpensive to manufacture, which issturdy in construction, which is dependable in operation, and which maybe employed to dry a plurality of different articles of clothing or thelike, or for drying objects which would be adversely affected byexposure to ordinary sunlight.

Fur-ther objects and advantages of the invention will become apparentfrom the following description and claim, and from the accompanyingdrawings, wherein:

yFigure l is a side elevational view, partly broken away, of an improveddrying apparatus constructed in accordance with the present invention;

Figure 2 is a vertical cross-sectional view, somewhat enlarged in scale,taken through the base portion of the improved drying apparatus ofFigure 1;

Figure 3 is a cross-sectional view taken on line 3 3 of Figure 2;

Figure 4 is a schematic wiring diagram showing the electricalconnections of the improved drying apparatus of Figures 1 to 3.

Referring to the drawings, II designates a circular base plate, and I2designates a cylindrical housing secured on the base plate. Designatedat I3 is a flanged cap member which is threadedly engaged with the topportion of the housing I2 and deiines a top wall for said housing.Secured inside the housing are a plurality of angle brackets I4, andmounted on said angle brackets is a supporting disc I5. Securedcentrally to the disc I5 is a bearing collar I6, and rotatablypositioned in said collar is an upstanding sleeve member I'I whichextends rotatably through the top cover I3. Secured in the sleeve memberI'I is a flexible metallic conduit I8, and secured to the end of theconduit I8 is the electrical lamp socket I9. Mounted in the socket I9 isthe infrared lamp 20. Designated at 2| is an electric cord whoseconductors are connected to the socket I9, said cord extending into thehousing I2 through the conduit I8 and through the sleeve I'I.

Designated generally at 22 is an electric motor which includes a eldcoil 23 and an armature 24, said armature being rotatably mountedbetween the horizontal supporting plate I5 and the laminated ironsupport member 25 shown in Figure 2, said support member being connectedto the plate member by depending vertical bolt elements 26. The coil 23is mounted on the laminated iron support member 25 and is arranged sothat magnetic flux from the coil causes the armature 24 to rotate.

Secured to the sleeve I'I is the horizontal crank arm 2l, and secured tothe top end of the shaft 28 of the armature 24 is another crank arm 29.The ends of the crank arms 21 and 29 are connected by a horizontal linkbar 30. The crank arm 29 is relatively short as compared with the link30, and is arranged so that rotation of the shaft 28 oscillates the endof the crank 21 through a relatively wide angle.

Designated respectively at 3| and 32 are switches mounted on the housingI2, said switches being connected respectively in the energizingcircuits of .the lamp socket I9 and the motor 22, as shown in Figure 4.Referring to Figure 4, it will be seen that the line cord 33 has one ofits conductors 34 connected respectively to the lamp socket I9 and themotor 22 with the switchesI 3| and 32 in series with the respectiveconnections, Therefore, the lamps 20 and the motor 22 may beindependently controlled by means of the respective switches 3l and 32.

In operation, the flexible conduit I8 is adjusted so that the lamp 2t isdirected toward the objects to be dried, the extent of excursion of thelamp being regulated by the point at which the flexible conduit I8 isbent. The lamp 2l) may be energized by closing the switch 3|, and tooscillate said lamp the switch 32 is closed to energize the motor 22.

It will be readily apparent that the infrared lamp 20 may be swung backand forth at a relatively wide angle of excursion, and that the radiusof oscillation of the lamp may be readily regulated by forming the bendin the conduit I8 at a desired location. The device may be employed as asun lamp as well as for drying garments or other objects, and may beemployed for drying garments which cannot be exposed to ordinarysunlight for fear of fading or for other reasons.

While a specific embodiment of an improved electrical heating apparatushas been disclosed in the foregoing description, it will be understoodthat various modifications within the spirit of 3 the invention mayoccur to those skilled in the art. Therefore, it is intended that nolimitations be placed on the invention except as defined by the scope ofthe appended claim.

What is claimed is:

A rotatable drier comprising a vertically disposed cylindrical housinghaving a removable top wall, brackets mounted on the inside surface ofthe side wall of the housing and projecting radially inwardly therefrom,a supporting disc seated in va horizontal plane on the brackets, anelectric motor depending from said disc and having an armature shaftrotatably disposed through the disc and arranged in a verticalplane. anupstanding tubular member rotatably disposed through the top wall of thehousing, a bearing Y red lamp, a first horizontal crank arm disposed insaid housing and secured to said tubular meinber, a second horizontalcrank arm secured to the shaft of the motor above the disc and ahorizontal link operatively connecting the crank arms.
